Your question is awfully generic but you could look at the Leatherman Wingman and Sidekick. Both are sub 7 ounces if I remember correctly. Want something truly carryable look at the Juice series from Leatherman. Want a small keychain type? Gerber Dime. Only Gerber product I have bought and not regretted in one way or another. I am sure they have other good products but somehow it is never the one I bring home...

I've got a couple of Juices stashed in various places. They are great little tools. I never tried a Gerber Dime but I do have a Leatherman Squirt on my keys. It's the only keychain size plier tool I've found that was actually sturdy enough to be really usable.

I am really looking for a "full-size" lightweight type muli-tool with all the usual blades, files, screwdrivers, etc. My thinking is you carry most equipment far more than you actually use it, but when you need it, it MUST work. For example---you could carry a 5" 1911, all steel 45 at about 40-42 ounces, plus extra mags and ammo (say another 50 rds), or you could carry an HK P2000 9mm at about 24 ounces and the same number of mags and ammo at almost half the weight. If you try to reduce your load, but keep similar effectiveness, I feel this is good and will try to apply this to most emergency equipment.

Cabellas multi tool cost 8$ and mine is great. I carry it all the time.
